Starter motor whirring?
Discussion
Sounds like the solenoid isnt kicking in. I'd suggest taking the motor out and getting it refurbed. It is a DIY'able job.
You need a good Allen key socket set, and a long extension to make it easier. Remove both air boxes to get to it. 'crack' the bolts off, ie give the socket a good sharp first bang to start with.

When you say 'the solenoid isn't kicking in' what do you actually mean - numpties guide if you have the time please.You need a good Allen key socket set, and a long extension to make it easier.

The trouble is, the solonoid dies from the heat, or dirt and sticks.
The solonoid is about a toilet tube size piggybacking the motor.
You could try giving it a gentle tap just to see if it frees it, but realistically you're lookign at a starter motor change really soon. If it does free it - treat it as a warnign sign.

So it is not the solenoid surely or nothing would happen. It sounds to me like the starter clutch has failed. The starter will spin/whirr but the starter clutch which transmits this drive to the engine has worn out gears so cannot turn the engine.

Okay here's my own guide to starter problems, and yes I've experienced them all but no two starters have exhibited the same problem.
1). Whirring - the clutch had gone - an easy check is turn the engine over and watch what happens to the belt on the top pulley (air con pump). If it jogs round then the starter clutch has probably gone. Had 3 of these in 5 days! New starter required or rebuild clutch.
2). Clicking - probably solonoid but check connections and keep fingers crossed. Maybe you can find a replacement solonoid but easiest option is new starter. The Tilton Super Stater solonoid is not interchangeable with any other brand (I've tried) - Had one of these.
3). Nothing - probably windings fried usually from staying engaged and running with engine - they don't last long this way it seems. Or dodgy connecion. If it's fried a replacement is required. Had one of these.
4). And my personal favourite. Gaunching or whizzing sound (which will only happens when a crowd of onlookers has assembled, oh how they mock, then oh how they jump when she shotguns into life) - failure of starter drive gear to engage with flywheel ring gear. The face of the starter gear spins against the fly wheel causing instant tightening of the sphincter muscle. Usually will require 2 to 3 goes to allow the teeth to find a mesh. Had two of these but gave up changing to cure as it's always started on either 2nd or third go. The symptoms vary depending (I believe) on heat transfer into or out of the bell housing making it expand or contact causing the starter to move in relation to the flywheel.
All in my opinion and experience and of course not to mention 6 starters in 2 years.
Other than all of the above it's been fine.
If anyone has any variations on the theme of starting a Cerby let us know I'm sure there must be more than 4.

It's a difficult question to answer I'll grant you. Some have had great success with starters that have failed within the hour for me. I had three attempts with one particualr variety over a weekend before redesignating it as an expensive paper weight.
My original Tilton was still going strong and swapped back in everytime a new and improved variety appeared and promptly failed. It was happily graunching away every now and again but always started. I've finally swapped to the (expensive) Race Metal. Yes it still fails to engage occasionally but it seems strong turns the engine over more quickly than any other I've tried and always starts but makes a much nicer type of graunch (more of a whizz) than the Tilton.
I really believe this is a tolerance issue (not me I've got plenty) around the bell housing and flywheel position. Some cars don't seem to suffer others do.
No help at all I know but it's going to have to go down as one of the many inponderables which seem to come as standard with the cerbera.
Good luck anyway.

Main reason for number 4 is the lack of lead in on the flywheel ring gear and the starter pinion. Had mine out when doing the clutch and there is very little there (what is there may have been worn in!) Look at any other car set up and all the teeth have a nice chamfer on them to improve engagement. Cerb's however do not see to employ this method.
